What are advantages and disadvantages of multistage amplifier?
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
Why the circuit amplifier created?
so you could amplify the signal without having to change the power source.
Which combination of n-type and p-type semiconducters would be used to amplify a weak electronic signal?
n-p-n
What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
Where does the energy come from to amplify the signal in a amplifier?
The energy comes from an additional power source, like a battery. Via various resistors and capacitors, the energy from the power source is put into the circuit. The signal that enters the ciruit will exit the circuit with a higher energy; the signal has been amplified.
